We're having a holiday breakfast/brunch from 7 - 10 next week. Our office has microwaves, a toaster and a small toaster oven. There is no stove or oven. It's about a 45 minutes drive in to the city, so whatever I bring will NOT be piping hot when it arrives. Any suggestions on something savory that will not suffer (bacterially or presentation-wise) from time spent at room temperature?? I'm looking for something besides the ever present sausage balls, pigs n a blanket, breakfast/hash brown casserole. Thanks in advance . . .
